21. CONFIRM THAT NO ITEMS SUCH AS AN ELECTRIC CABLE OR CONDUIT ARE BURIED

INSIDE. In places where electric wiring may be hidden behind a wall, floor, ceiling, etc.

do not hold or contact any metal parts of the poweer tool. In such cases, metal parts

could become electrically live and present a serious shock hazard.

22. KEEP THE RIGHT PARTS IN THE RIGHT POSITIONS. Do not remove covers and screws

which have been factory-mounted. They perform important respective roles. Keep them

in the original positions.

23. SECURELY MOUNT ACCESSORIES AND BLADES TO THE POWER TOOL MAIN BODY.

Extra care must be taken when using the power tool on elevated location (such as a

roof ladder, scaffold, or the like) to prevent injury to someone underneath in the event

the power tool and/or accessory should drop.

24. ALWAYS KEEP THE MOTOR AIR VENT FULLY OPENED. A constantly open motor air

vent is necessary to allow air to come in and out for cooling the motor. Do not allow it

to become clogged up, even if dust is blown through it.

25. OPERATE THE POWER TOOL AT THE RATED VOLTAGE. Operate the power tool at

voltages specified on its nameplate.

26. NEVER TOUCH THE MOVING PARTS. Never touch the moving parts such as blades,

bits, cutters and others.

27. STOP OPERATION IMMEDIATELY IF ANY ABNORMALITY IS DETECTED. Should the

component part with a new one, adopt the same type of new part. Also, never attempt

to repair the power tool yourself. Bring it to an authorized service center for repair.

WARNING:

Some dust created by power sanding, sawing, grinding, drilling, and other construction

activities contains chemicals known to the State of California to cause cancer, birth

defects or other reproductive harm. Some examples of these chemicals are:

• Lead from lead-based paints,

• Crystalline silica from bricks and cement and other masonry products, and

• Arsenic and chromium from chemically-treated lumber.

Your risk from these exposures varies, depending on how often you do this type of

work. To reduce your exposure to these chemicals: work in a well ventilated area, and

work with approved safety equipment, such as those dust masks that are specially

designed to filter out microscopic particles.

GROUNDING INSTRUCTIONS

This power tool should be grounded while

in use to protect the operator from electric

shock. The power tool is equipped with a

three-conductor cord and three-prong

grounding type plug to fit the proper

grounding type receptacle. The green (or

green and yellow) conductor in the cord is

the grounding wire. Never connect the green

(or green and yellow) wire to a live terminal.

If your unit is for use on less than 150 volts,

it has a plug that looks like that shown in

sketch (A) in Figure on the right. An adapter

(see sketches (B) and (C)) is available for

connecting sketch (A) type plugs to two-

prong receptacles. The green-colored rigid

ear, lug, or the like, extending from the

adapter must be connected to a permanent

ground, such as a properly grounded outlet

box.

WARNING:

The grounding adaptor, sketch (C), is

prohibited in Canada by Canadian Electrical

Code Part 1. Therefore, the instructions for

its use are not applicable in Canada.

EXTENSION CORD

Use only three-wire extension cords that have three-prong grounding-type plugs and three-

pole receptacles that accept the power tool’s plug. Replace or repair damaged extension

cord.

Make sure your extension cord is in good condition. When using an extension cord, be

sure to use one heavy enough to carry the current the power tool will draw. An undersized

cord will cause a drop in line voltage resulting in loss of power and overheating. Table

below shows the correct size to use depending on cord length and nameplate ampere

rating. If in doubt, use the next heavier gage. The smaller the gage number, the heavier the

cord.

APPLICATION

This demolition hammer should be applied to breaking concrete, chipping off concrete,

grooving, bar cutting, and driving piles in installation of piping and wiring, sanitary facility

installation, machinery installation, water supply and drainage work, interior jobs, harbor

facilities and other civil engineering work, etc.

PRIOR TO OPERATION

1. Power source

Ensure that the power source to be utilized conforms to the power requirements specified

on the name plate of this demolition hammer.

2. Power switch

Ensure that the power switch is in the OFF position. If the plug is connected to a power

receptacle while the power switch is in the ON position, this demolition hammer will

start operating immediately, inviting serious accident.

3. Extension cord

When the work area is remote from the power source, use an extension cord of sufficient

thickness and rated capacity. The extension cord should be kept as short as practicable.

4. Confirm the power receptacle

If the power receptacle loosely accepts the plug, the receptacle must be repaired. Contact

the nearest authorized service center for repair service.

If such a faulty receptacle is used, it may cause overheating, resulting in a serious

hazard.

5. Confirming condition of the environment

Confirm that the work site is placed under neat, clean conditions conforming to

prescribed precautions.

6. Feeding oil (Refer to the paragraph on oil feeding at page 9 below.)

Prior to using this demolition hammer, remove the oil gauge and do not fail to fill the

oil tank with the provided oil. (Although the oil tank is built in, it contains only a small

quantity of oil when shipped from the HITACHI Works.)

7. Mounting an accessory, such as a bull point, a cutter, etc..

(1) With the retainer directed backward, insert the accessory shank portion into the

hole on the front cover. (Fig. 2)

(2) Swing the retainer back into place so that it engages the accessory shank portion

and prevents accessories from coming out of front cover. (Fig. 3)

NOTE:

Use a manual hammer to open/close the retainer as it is too heavy to move by hand.

NOTE:

When removing the accessory, such as a bull point, a cutter etc., follow the above procedure

in reverse order.

OPERATION

1. Pull the trigger switch after applying the tip of the bit to the

crushing position.

In some cases, it is necessary to punch the tip of the bit against

the crushing position forcibly in order to begin the striking

stroke.

This is not due to malfunction of the power tool. It means

that the safe guard mechanism against no-load striking is

working.

2. Operate this demolition hammer by utilizing its own weight.

The performance will not be better even if it is pressed or

thrust forcibly against the work surface.

Hold this demolition hammer with a force just sufficient to

counteract the reaction.

CAUTION:

Sometimes the power tool does not begin the striking stroke even

when the motor rotates because oil has become thick.

If the power tool is used at low temperatures or if it is used after

a long idle time, this demolition hammer should be kept running

for about five minutes in order to warm it up.

OIL FEEDING

CAUTION:

Prior to oil feeding, always disconnect the plug from the power supply receptacle. Since an

oil chamber is built in this demolition hammer, it can be used for approximately 20 days

without supplying oil, assuming that this demolition hammer is used continuously 3 ~ 4

hours a day.

Feed oil into the oil tank as described below before using this demolition hammer. (See

Figs 5 and 6)

1. Feed oil without fail before no oil is visible in the oil gauge window when this demolition

hammer is held upright.

2. Before feeding oil, remove the oil gauge with the provided wrench. Be careful not to

lose the rubber packing attached under the oil gauge.

Fig. 3Fig. 2

3. Check the oil level once a day, confirming that oil is enough.

4. After feeding oil, securely clamp the oil gauge.

NOTE:

As an optional accessory, oil for the HITACHI Demolition Hammer (one liter) is sold separately.

Use this oil when oil in the tank becomes less than the level indicated in Fig. 6 below.

MAINTENANCE AND INSPECTION

CAUTION:

Be sure to switch power OFF and disconnect the plug before and during maintenance and inspection.

1. Inspecting this demolition hammer

Since use of a dull accessory, such as a bull point, a cutter, etc., will cause motor

malfunctioning and efficiency degraded efficiently, whet it or replace with a new one

without delay when abrasion is noted.

2. Inspecting the mounting screws:

Regularly inspect all mounting screws and ensure that they are properly tightened.

Should any of the screws be loose, retighten them immediately. Failure to do so could

result in serious hazard.

3. Inspecting the retainer (Fig.2 and 3)

The retainer may become loose due to excessive use. Always, pay attention to its proper

functioning to securely hold the accessory shank portion. If any wear and tear is found,

bring this demolition hammer to an authorized service center for maintenance service.

4. Inspecting the carbon brushes: (Fig. 7)

The motor employs carbon brushes which are

consumable parts.

Since an excessively worn carbon brush results in motor

trouble, replace the carbon brush with a new one which

has the same carbon brush No. shown in figure 7 when it

becomes worn to or near “wear limit”.

In addition, always keep carbon brushes clean and ensure

that they slide freely within the brush holders.

5. Replacing a carbon brush

The carbon brush can be removed by removing the cap cover, cap rubber and brush

cap in that order at the interior.

NOTE:

Due to HITACHI’s continuing program of research and development, the specifications herein

are subject to change without prior notice.
